Schwannomas (neurinoma, neurilemmoma) are benign slow-growing encapsulated tumours originating from well-differentiated myelin-producing Schwann cells or nerve fiber sheet cells at the glial-Schwann cell junction. Hypoglossal nerve schwannoma mostly develops in the intracranial and extra-cranial segment or in both intracranial and extra-cranial segment forming a dumbbell shape tumour. The peripheral hypoglossal schwannomas are very rare. We present a case of right hypoglossal nerve schwannoma in a 46-year-old female who presented with headache and neck pain since 2 weeks with deviation of tongue to right side since 1 week...

Pontine tegmental cap dysplasia is a rare hindbrain malformation syndrome with a hypoplastic pons, a tissue protrusion into the fourth ventricle, and cranial nerve dysfunction. We here report clinical, imaging, and genetic findings of the first extremely low-birth-weight preterm infant with pontine tegmental cap dysplasia born at 25 weeks of gestation and provide an overview of 29 sporadic cases. A prenatally diagnosed hypoplastic and rostrally shifted cerebellum was indicative of a hindbrain defect and later identified as an early sign of pontine tegmental cap dysplasia in our patient...

OBJECTIVE The rectus capitis lateralis (RCL) is a small posterior cervical muscle that originates from the transverse process of C-1 and inserts onto the jugular process of the occipital bone. The authors describe the RCL and its anatomical relationships, and discuss its utility as a surgical landmark for safe exposure of the jugular foramen in extended or combined skull base approaches. In addition, the condylar triangle is defined as a landmark for localizing the vertebral artery (VA) and occipital condyle...

Oral appliance therapy (OAT) is the main therapeutic alternative to continuous positive airway pressure (CPAP). OAT has been recommended as an appropriate first-line treatment option for moderate obstructive sleep apnea-hypopnea syndrome (OSAHS) in patients without severe cardiovascular comorbidity. The lower efficacy of OAT in reducing sleep-disordered breathing could be offset by a higher compliance relative to CPAP, resulting in similar health outcomes in terms of sleepiness, neurobehavioral functioning, quality of life and blood pressure...

BACKGROUND: Drug-induced sedation endoscopy (DISE) is a diagnostic procedure which allows evaluation of the collapsibility of the upper airway. According to expert opinion, it is possible to imitate nocturnal collapsibility and perform a realistic investigation of the site of obstruction and vibration. This should enable sufficient and precise therapeutic advice to be given solely on the basis of clinical assessment. OBJECTIVE: The current publication critically evaluates the present state of development of DISE and its potential indications...

OBJECTIVE: Distal branches of the C1 nerve that travel with the hypoglossal nerve have been well investigated but relationships of C1 and the hypoglossal nerve near the skull base have not been described in detail. Therefore, the aim of this study was to investigate these small branches of the hypoglossal and first cervical nerves by anatomical dissection. METHODS: Twelve sides from six cadaveric specimens were used in this study. To elucidate the relationship among the hypoglossal, vagus, and first and cervical nerve, the mandible was removed and these nerves were dissected under the surgical microscope...

OBJECTIVES/HYPOTHESIS: Selective upper airway stimulation (sUAS) of the hypoglossal nerve is a useful therapy to treat patients with obstructive sleep apnea. Is it known that multiple obstructions can be solved by this stimulation technique, even at the retropalatal region. The aim of this study was to verify the palatoglossus coupling at the soft palate during stimulation. STUDY DESIGN: Single-center, prospective clinical trail. METHODS: Twenty patients who received an sUAS implant from April 2015 to April 2016 were included...

CONCLUSION: Unusual primary tumors of the facial nerve should be considered in patients with progressive facial paralysis, especially if this is accompanied by hearing loss or vertigo. Misdiagnosis could increase the difficulties of operation, diminish the chance of facial nerve reconstruction, and increase the likelihood of poor reconstructive outcomes. OBJECTIVE: This paper was to determine the characteristics of facial nerve primary tumors misdiagnosed as tumor-free conditions many years prior, and to describe appropriate treatments...

BACKGROUND: A pneumocele occurs when an aerated cranial cavity pathologically expands; a pneumatocele occurs when air extends from an aerated cavity into adjacent soft tissues forming a secondary cavity. Both pathologies are extremely rare with relation to the mastoid. This paper describes a case of a mastoid pneumocele that caused hypoglossal nerve palsy and an intracranial pneumatocele. CASE REPORT: A 46-year-old man presented, following minor head trauma, with hypoglossal nerve palsy secondary to a fracture through the hypoglossal canal...

OBJECTIVE: Retrograde neuronal cell death does not occur in mature motoneurons following the axonal injury of peripheral nerves. However, a previous study suggested that retrograde neuronal cell death does occur in adult rats after the creation of double lesions on the hypoglossal (XII) nerve based on a substantial decrease in the number of XII neurons. Using stereological methods, we examined neuronal apoptosis in XII neurons and the total number of XII neurons following repeated crush injuries to the XII nerve...

KEY POINTS: Hypercapnia or parafacial respiratory group (pFRG) disinhibition at normocapnia evokes active expiration in rats by recruitment of pFRG late-expiratory (late-E) neurons. We show that hypercapnia simultaneously evoked active expiration and exaggerated glottal dilatation by late-E synaptic excitation of abdominal, hypoglossal and laryngeal motoneurons. Simultaneous rhythmic expiratory activity in previously silent pFRG late-E neurons, which did not express the marker of ventral medullary CO2 -sensitive neurons (transcription factor Phox2b), was also evoked by hypercapnia...

Background: Identifying genes that are essential for mouse embryonic development and survival through term is a powerful and unbiased way to discover possible genetic determinants of human developmental disorders. Characterising the changes in mouse embryos that result from ablation of lethal genes is a necessary first step towards uncovering their role in normal embryonic development and establishing any correlates amongst human congenital abnormalities. Methods: Here we present results gathered to date in the Deciphering the Mechanisms of Developmental Disorders (DMDD) programme, cataloguing the morphological defects identified from comprehensive imaging of 220 homozygous mutant embryos from 42 lethal and subviable lines, analysed at E14...

The vast majority of benign tumors of the cerebellopontine angle, temporal bone, and parotid gland can be successfully resected without permanent injury to the facial nerve. Malignant tumors or recurrent disease may require facial nerve sacrifice, especially if preoperative facial paresis is present. This article will present case examples of the various methods to reconstruct facial animation after lateral skull base resections that require sacrifice of cranial nerve VII, and the associated mimetic facial musculature...

PURPOSE: Many dental procedures are at risk of injuring the lingual nerve. We performed this study to better elucidate the microanatomy that exists between the ipsilateral lingual and hypoglossal nerves so that iatrogenic injury can be avoided. METHODS: Adult human cadaveric tongues (ten sides) underwent Sihler's staining to identify the microanatomy between the lingual and hypoglossal nerves. RESULTS: The lingual nerve entered the middle part of the anterior two-thirds of the tongue from its lateral side and divided into two to four thick branches...

Isolated paralysis of hypoglossal nerve is uncommon, generally being associated with other neuropathies. A careful differential diagnosis is necessary to recognize the underlying diseases, some of which can be life-threatening. The authors report a patient of an 80-year-old woman presenting with an isolated hypoglossal palsy, mimicking a tongue neoplasm. Through a careful clinical workup and thanks to the aid of the imaging, it was possible to identify the presence of signal alterations due to a subacute denervation of the affected hemitongue and to exclude the presence of a tumor...
